2. Information on the collection of personal data

2.1. General

GIZ processes personal data exclusively in accordance with the EU General Data Protection Regulation (GDPR) and the German Federal Data Protection Act (Bundesdatenschutzgesetz, BDSG).

Personal data are, for example, name, address, email addresses and user behaviour.

GIZ only processes personal data to the extent necessary. Which data is required and processed for which purpose and on what basis is largely determined by the type of service you use or the purpose for which the data is required.

2.2 Collection of personal data when visiting our website 

When visiting the website, the browser used automatically transmits data that is saved in a log file. GIZ itself processes only the data that is technically required in order to display the website correctly and to ensure its stability and security.

Each time the website is accessed, the data stored includes, but is not limited to, the page that is viewed, the IP address of the accessing device, the page from which the user was redirected, as well as the date and time of access. A detailed list of the data stored is shown here.

Further information on data storage and transfer

GIZ is obliged to store the data beyond the time of the visit in order to ensure protection against attacks against GIZ’s internet infrastructure and federal communications technology (legal basis: Article 6 (1) e GDPR in conjunction with Section 5 of the German Act on the Federal Office for Information Security (BSIG). In the event of attacks on communications technology, this data is analysed and used to initiate legal and criminal action.

Data that is logged when accessing the GIZ website is only transferred to third parties if there is a legal obligation to do so or if the transfer is necessary for legal or criminal prosecution in the event of attacks on federal communications technology. Data will not be passed on in any other cases. This data is not merged with other data sources at GIZ.

2.3 Cookies

When you visit the GIZ website, small text files known as ‘cookies’ are stored on your computer. They are used to make the online presence more user-friendly and effective overall. Cookies cannot run programs or infect your computer with viruses.

The GIZ website uses cookies that are automatically deleted as soon as the browser on which the page is displayed is closed (referred to as temporary cookies or session cookies) This type of cookie makes it possible to assign various requests from a browser to a session and to recognise the browser when the website is visited again (session ID).

2.4 Matomo (User analysis)

On its website, GIZ uses the web analysis service "Matomo” to analyze usage data. The data is stored and evaluated completely anonymously.

Cookies are used to collect information on the usage behaviour of this website, including the IP address of the requesting computer, which is stored in abbreviated form, and transmit this information to the server. The data is made anonymous there and stored for the purpose of usage analysis. After the anonymization, an assignment to the inquiring computer or connection is no longer possible according to the current state of technology. The information generated by the cookie is only passed on to the internally operated server. It will not be passed on to third parties.

We only collect your usage data if you consent to the use of cookies by accepting it either via the cookie banner that is displayed when you access our website or by following the link under "information on opting out". Therefore, our processing is based on Art. 6 para. 1 lit. a) GDPR.

Information on opting out

It is possible to withdraw your consent and/or object to the processing of user data for the analysis of user behaviour. Here, you have the option to deactivate the processing of user data.

2.5 Webinars

Webinars and webinar series are offered on the website. When users want to participate in a webinar, they are asked to complete a registration form by indicating their contact information (name, e-mail address, country) as well as information about their organization (e.g., name, type of organization).

GIZ uses the contact information to conduct the webinars (e.g., for sending invitations, preparing a participant list, etc.) and to inform participants about future webinars which are similar to the ones they have registered for. In addition, information about the organization as well as answers to topical questions in the registration form are anonymized and analyzed to learn more about the participants’ background and interests.

For conducting the webinars GIZ uses the third-party video conference solutions Cisco Webex and Microsoft Teams. Microsoft and Cisco are engaged as GIZ’s sub-processors in a GDPR-compliant manner. We refer to Cisco’s privacy policy and Microsoft’s privacy policy for information on how they process personal data.

The processing of personal data for conducting the webinars is based on Art. 6 para. 1 lit. b) GDPR (performance of our contractual duty to conduct the webinar) and lit. e) GDPR (processing is necessary for performing a task in the public interest).

Webinar recordings

Webinars are recorded to provide information shared in the webinars. This also means that the audio and video signal of participants will be recorded. Therefore, at the beginning of each webinar and/or webinar series, we will ask for the participants’ consent to the recording of their audio and video signal. If a participant does not consent to the recording, he/she may not share his/her audio and/or video signal during the webinar.

The recording of the video and/or audio signal in the context of webinars is based on your consent in accordance with Art. 6 para. 1 lit. a) GDPR where it concerns providing information. It is based on Art. 6 para. 1 lit. e) GDPR (performance of a task in the public interest) where GIZ processes the recording internally to provide information shared in the webinar.

4. Processing of personal data in connection with social network use

On its website, GIZ invites users to visit its company presence on social networking sites and platforms including, but not limited to, Instagram, LinkedIn, YouTube and Facebook.

These online presences are operated in order to interact with the users that are active on these sites and platforms and to inform them about projects and services. By clicking on a social network’s logo, the user is redirected to the Grüner Knopf (Green Button) presence on the respective network.

When users visit the platforms, personal data is collected, used and stored by the operators of the respective social network, but not by GIZ. This is also the case even if the users themselves do not have an account with the respective social network.

The individual data processing operations and their scope differ depending on the operator of the respective social network. GIZ has no influence on the collection of data or its further use by the social network operators. We are not fully aware of the extent to which, where and for how long the data is stored; to what extent the networks comply with existing obligations regarding erasure; what analyses are conducted and links established with the data; and to whom the data is disclosed.

Access to GIZ social media sites is subject to the terms of use and privacy policies of the respective operators. Click here for the contact details and links to the data privacy policies of the social media on which GIZ maintains a presence.

By operating the Facebook page, GIZ offers a modern communication and information option. The processing of personal data in connection with the operation of the Facebook page is based on Article 6 (1) e GDPR.

As the operator of the fan page, GIZ is jointly responsible with Facebook for the processing. However, primary responsibility for processing Insights data lies with Facebook. Facebook therefore fulfils all obligations under the GDPR with regard to the processing of Insights data (including but not limited to Articles 12 and 13 GDPR, Articles 15 to 22 GDPR and Articles 32 to 34 GDPR). The rights of the data subject can be asserted either with GIZ or Facebook. Should you contact GIZ, GIZ is obliged to forward all relevant information to Facebook.
